Arlene Foster has backed the DUP's East Antrim MP Sammy Wilson, insisting he is "not a racist".

Mr Wilson was embroiled in controversy when footage shot by the BBC emerged of him appearing to agree with a member of the public's "get the ethnics out" comment.

In his brief conversation with the member of the public, Mr Wilson told the man: "They are doing a programme on the BBC about should we stay in the European Union or get out of it, so I am going around talking to people and then they are going to do an interview with me."

The man then said: "I'd say get out of it... between you and me get the ethnics out too."
